It is an object of this invention to pro` vide an kimproved yarticulated car construction in which a pair of relatively movable bolster sections individually support the side bearings for the respective carends, and jointly supporta center bearing which f is apcommon ysupport for both ycar ends. It is also an object of this invention to provide an yimproved articulated ycar construction comprising a connection betweenthe car underframes particularly adapted for use in connection with the truck center bearing above-mentioned to permit relative movement of the car bodies and which will permit of the ready separation of the bodies without an excessivelifting of either body and the separateparts otwhich may be readily secured to and disconnected from the individual underirames. y y

In the drawings, the invention is shown in connection with a truck of suitable construction7 comprisingside frames 1 having compression members 2 and tension members 4 which are secured together at their ends and secured to pedestals 6. The pedestals are joined by the tie bars 8 which pass beneath and are secured to thetension members 4at the center of the truck.k Mounted in the pedestals 6 are the journal boxes 10 in which are journaled the axlesk 12 carrying the wheels 14, the journal boxes 10 supporting the sideframes by means `of springs 16.

Brackets 18 are mounted on the tension In'embers 4 adjacent the centers thereof and on the correspondingfbracketsk of the opposite tension members are secured the transoms .2O f

which 'connect the side frames together. j

The corresponding ends of the transoms 20 are joinedby the members 22 having angular legs 23 which are connected to the transoms 2O and are connected by channel shaped cross rpieces v25 havingfone flange fastened to the compression membersy 2 of the side frame. The upper edges of` the transoms 20 except where `cut away to receive the members 22 are provided with outwardly and. downwardly projecting flanges 24, the horizontal portions of which yare secured yat their `ends to brackets 26 which are also secured to the compression members 2y yand the member`s`22. Mounted on the brackets 26 are swing links' 2f i u 1,727,667

28 connected at their lower ends by the adjustable spring plank supports 30, the ends of which extend through vopenings in the swing links and are secured therein by the pins 31. Mounted on the supports 30 are the spring seats 32 having the curved surfaces 34 for engagement with the supports 30 and projectinglugs 36 which engage upon opposite sides of the spring clips 38. The spring seats 32 arealso provided with the iiangesl 40 which extend upon opposite sides ofthe elliptical springs 42 and extend to and are secured to flanges 44, the flanges 44 and the innercends of the flanges 40 of the spring seats 32 at opposite sides of the truck being connectedby the oppositely disposed angles 46 to form the spring plank.A

Extending from side to side of thev truck and having its opposite ends engaging the spring clips .48 which secure the upper portions of the springs 42 together is a bolster 50 comprising a plurality of similar but oppositely disposed sections 52 and 54, the individual bolster sections being independent ly supported upon separate springs 42 as shown in Figs. 1 and 5 or upon separate groups of springs where additional springs are required. Each ofthe bolster sections is substantially rectangular at its ends and channel-shaped at its ycenter and the bolster sections are arranged so that the webs 55 are together at the centers of the holsters. The center portion of each bolsterk section is depressed lbelow the end portions and has-its web curvedv inwardly into the body of the 'bolster section as at 57 so that whentwo sections are placed together there is formed anr lopening 59` of the full depth of the web and elongated in the direction of the length of the bolster. At the center of the bolster sections, the Aweb is ofy greater height and is so shaped that the upper surface of the bolster "section forms an arc as at 61 having its center of curvature in the axis of the' opening '60 in 'the web 55. Formed integral with the `'bolster sections adjacent each end thereof are,

side bearings 62v which' project above 'the `levelof the ends of they bolster sections and have outwardly lprojecting Y forr'ned integral therewith. At the ends, the

portions 64 inner or adjacent webs 55 of thesections are extended to form' flanges 66 and 67 which extend between the bolster ends and side bearings62. The tlanges' are provided with perforations 68v through which pass rivets 70 which Vsecure the U-shaped clips 72 to the lianges 66. kThe rivets 70 and clips 7 2 serve to secure the'y bolster sections together while at the same time permittingof relative movements of lthe bolster' sections.k If desired,

"the Ushaped clips 72 may also be made inl tegralwith the flanges 66 thereby dispensing withthe rivets 70.` At'each end, each bolster section is provided with a wear plate 80 'which engages a corresponding wear plate lar .flange 90 which surroundsan opening in the center of the center bearing and an outer circular flange 88 which, with the flange 90, defines a flat annular seat in which is supported a body bearing 92 provided with an opening to receive the flange 90, suitable bearing lining 93 being placed between theltruck1 and body center bearings. The body bearing 92 is formed integral with body bearing bracket 94 of substantially rectangular shape` whichis received in a pocket' 96 of a pocket casting 98 mounted between the ends of the longitudinal sills 100 of the underframe of one of the car sections supported by the truck. A pin 102 passing' through openings in the casting 96 Aand bracket 94 secures the bracket 94 in position in' the casting 96. The body -center bearing 92 is formed with a concave upper surface 103 vin'whicli is mounted a filler block 104 shaped tok fit the surface of the center bearing and provided with an opening to receive the iange 90. The iller block 104 has' a convex upper surface 106 upon which is mounted a body center bearing 108 having a surface109 conforming to the surface 106y and formed integral with a bearing bracket 110 which iits in a pocket 112 of a pocket casting 114 mounted between the longitudinal sills 116 of the underfr'ame of the other car section on this truck. The body bearing vbracket 110 is secured in position in the pocket casting 114 by a pin 118. Each of the underframes comprises end sills 142 ito which are secured body side bearings 144 which engage the respective side bearings 62 and the extensions 64 thereof.

Gpenings in the body center bearing 108 and the openings in the filler `block 104 and bodyV center bearing Q2-aline with the' opening in the truck center bearing 84 and with the openings 59 formed by the inwardly curved portions of the webs 55 of the bolster sections. Extending through the alined openings is a king pin or bolt 120 having a head 121 resting upon a web 123 ofv the body center bearing 108 and provided with an eye 125 for use in removing the pin. Adjacent the head 121, the body of the pin 120 for a portion of its length is of a diameter to tin the openings in the body center bearing 108 and filler block 104 so as to prevent undue play betweenl the bearing 108 and the liller block. The remainder of the body of the pin 120 is of less diameter and lits the opening in the truclr center bearing 84 and the opening 59 formed in the bolster, there being suiticient clearance to permit ready movement of the pin 120 in the directiono't the length of the opening 59. The lower end of the pin 120 projects through a collar 122 provid-cd with trunnions 124 which engage in the openings 60 in the Webs of the bolster sections. A nut 126 threaded on the lower end oit pin 120 secures the pin in position and secures the body center bearings 92 and 108, the filler block 104 and truck center bearing 84 together' and to the bolster 50.

Removal of the pin 120 will permit of the separation of the car sections by removing the center bearing 108 trom the filler block 104, an operation which involves but a slight elevation of the car section. The filler block 104 may then be removed and the body center bearing 92 removed from the truck center bearing 84, an operation which Will require but the usual elevation of the car section.

Mounting the king pin 120 in the pivotally mounted collar 122 gives a construction which permits of the independent pivotal movement ot' the bolster sections about the trunnions 124 as an axis, the truck center bearing 84 traveling on the arc-shaped portions 61 ot the bolster sections and the pin traveling in the opening 59. Stops 186 secured to the web of one ot the bolster sections by the bolts 138 limits the movement of the truck center bearing 84 with respect to that bolster section While leaving the other bolster section free with respect to the truck center bearing.

Mounting the individual bolster sections upon independent springs or groups ot springs permits of independent movement ot the ends oit the bolster sections so that the carbodies engaging the respective side bearings may rock with respect to each other, this rocking movement being permitted by the shape ot the engaging surfaces ot the body center bearings and filler block and the engaging surfaces of the body sections and truck center bearing.

It will be noted that the body center bearing 108 in Fig. 3 abuts the forward end oit the center bearing bracket-s 94 so that buit'- ing stresses are transmitted directly through the bearing bracket 94 and center bearing 108 and through the bearing brackets and pocket castings to the underframes Without exerting any stresses upon the pin 120 and pins 102 and 118. It will also be noted that the pin 120 forms a secure connection between the bolster and the body center bearings so that the driving` stresses may be ltransmitted from the motor 140 through the bolster to the undertrames of the cars. It

Will also be noted that While the openingl 59 permits of movement of the'lring pin 120 longitudinally of the bolster', movement of the pin 120 transversely ot the bolster is prevented by the Webs 55.
